Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow, drawing the eye along its tapered points. This semi-set platinum mounting offers a sleek, modern-minimal frame designed to showcase an 8 x 4 mm marquise center with subtle accent stones that enhance its architectural clarity.

Crafted in Williamsburg, the band’s low-profile setting ensures a comfortable fit for daily wear, while the polished platinum lends a cool, enduring strength. Each piece is meticulously finished and inspected in-studio, reflecting a commitment to precision and understated elegance.

Our lab-grown diamonds provide the same scintillating fire as mined stones, with a lighter environmental footprint and traceable origins.

This ring suits those who appreciate clean lines and confident structure, especially flattering on slender fingers or as a refined stackable piece. Its low profile and smooth edges make it glove-friendly and easy to wear every day.

Resizing is available to ensure a perfect fit, with typical lead times aligned to our Brooklyn studio’s careful handcrafting process.
